     <h1>class <tt>Color</tt> </h1>
     <p>A Color object is used to represent a color for drawing on a <a href="Canvas.html">Canvas</a>. Color  objects are immutable.<br>
</p>
<p>Support for alpha values in colors is platform-dependent. On
platforms with no alpha support, alpha values always read as 1.0. Even
if colors with alpha are supported by a platform, alpha values may be
ignored by some operations.<br>
